Thanks Wiltron. Daughter was thinking of adding me to a family plan on her account in a couple of months when my plan runs out with another carrier. I was naturally thinking of the new iphone 4g after the introduction dust settles. However I stream net radio in the car and frequently use Slingplayer Mobile...so AT&T's announcement of ending unlimited data...doesn't seem like good news to me. So do we rush down now and end up with a 3gs to get the unlimited data...or will the 2gig a month with the 4g be fine down the line. At 120kbps you'd have 16,666 hours of data stream a month which only has 720 hours in a whole month. If that's accurate I'm ok. Who could ever use more than that? But does all media use the same amount of data stream...ie audio alone (Pandora) versus video/audio (Slingplayer Mobile). Is there anyway to determine that? Unfortunately I'm potentially in a situation to have to figure it out fast.

That's a hard one to answer bc 2gb seems like alot but if u are constantly streaming music, pandora, slingbox, etc... That will go fast and get VERY expensive for the overage. I use pandora, iheartradio, Dan Patrick show daily during my 8 hours at work and normal Internet usage and I average around 4-4.5gb monthly. And remember too that there are alot of Apps that use data constantly, which is why the iPhone required unlimited data in the first place, so take that into acct also. Hope that helped

My $0.02 would be to get a 3g or 3Gs now from ebayvor craigslist and get the unlimited data for $30 that way u don't have to worry about overages and then when u upgrade to the new iPhone u can keep ur unlimited plan. The new data plans are for new customers, so those who already have it can keep it, even when u upgrade. Just my opinion.

Great thought about picking up a used iphone now...and upgrading it later. Just heard on local tv news that 2gigs a month is good for 10,000 emails, uploading 50 pics to social networking site, or watching 200 minutes of video. Thus 2gigs doesn't sound good for me. I'm heading to an AT&T store to see if I could get an add on account now with low minutes...and start paying for it...before I pick up a used phone and activate it next week...or if I could even wait and get an iphone 4g and activate it then. Actually looked and my current plan is up in 6 weeks...so paying for a month and a half of unused service on low minutes would be a small sacrafice...to get locked into unlimited data. I post what I find out when I get back.

Could you get on your daughter's account now with a new 3GS, lock into the unlimited data and then within 30 days return the new 3GS citing you didn't realize a new iPhone was going to come out and you want to get that instead, all the while letting you get grandfathered in to the unlimited data plan?

I'm not sure if the iPhone or AT&T has the 30 day trial period on hardware, but if they do it makes sense in my head.

Got back from AT&T store. They said unlimited data available thru Sunday. Monday it's gone. They also said I could add a line on daughters account thru Sunday and get unlimited data with a temporary number without purchasing or activating a phone. Then when I want to buy one and activate it, I could get my number transferred to it. Sounds like a plan. I did check prices on used iphones 3gs on craigslist and they are all about $300 and up! So after Monday's announcement about the price and availability of the iphone 4g...(and perhaps lower price on 3gs too) I can figure out what to do. I also got an answer about the data rate for SlingMobile on the iphone from the sling forum. They said 113MB an hour...very similar to Wiltron's post. So it looks like on 2 gigs you could stream it for about 18 hours a month. Daughter's working 12+ hr. overnights @ hospital Thursday thru Saturday nights. Have to try to intercept her before Monday. Thanks for everyone's help...

Thanks rdiddy. Got Wal-Marts around. I'll check their stock. Daughter says she's up for it Sunday. Now it's...how do I get 10 years of Palm OS pim over to the new tool? From the little I've read, it could be challenging... Appreciate all your help too Wiltron. Great folks on this forum!
